To allwhom it mag/concern:

Be it lmownthat I, Qnosco ,G. ,VooLsoN, a citizen of the United Stat es, resid ing in New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Ventilated Interlocking clinker-Bars for Furnaces, of which the following is a specification.

This invention relates-to clinker furnaces in general, and more particularly to ventilated clinker grinders.

The present invention contemplates an improved clinker furnace construction, comprising a supporting guide-bar,usually tubular or otherwise .interiorly ventilated, sectional interlocking crusher-s, or toothed grinder rings, supported and vibrated or rotated upon said supporting guide-bar and spaced and centeredthereon to form ventilating passages for said crusher or grinder members. 7

These and other features, capabilitiesand advantages of the invention. will ppear from the subjoined detail description of specific embodiments illustrated in the accompanying drawing, in whic h Figure 1, is a fragmental view, partly in section, of the rear. end of a furnace made in accordance with the present invention, which is shown applied thereto;

Referring to the drawings:

Theembodiment illustrated in Figs. 1 to 7 inclusive, comprises essentially an inner wall of masonry I, an outer furnace-wall member 0, and a crusher or grinder-bar construction C supported on said walls I and O.

The inner wall 1. is composed of a concrete-base12 anda brick-work wall member 11, disposed above the same, between which the exhaust pipe or fine connection 18 extends. On the base 12 inwardly ofthe brickwork wall member 11 there is disposed the housing 14, into which the inner end of the crusher or grinder bar construction G extends, and also the shell 15 which encircles the inner end of the crusher or grinder bar construction G and is secured to the inner end of the pipe connection 13. The shell 15, as illustrated is preferably composed of two half sections, which are secured around the inner end of the exhaust pipe or flue connection 13, by means of the screws 16, for the reception of which suitable bosses 17 are formed on the shell sections 15.

The crusher and grinder carrying bar construction C comprisesessentially a supporting guide-bar 18, sometimes provided with a ventilating bore 19 extending from one end to the other thereof for the purpose of ventilating and cooling such guide-bar, by the free circulation of air therethrough. The inner end of such supporting guide-bar 18, is externally screw threaded, shown at 20, to engage the internal screw threaded portion21 of the integralbearing and-abutment member 22; the inner central rear hubport on 21 of-wh ch is rigidly oonneQttd to the cylindrical outer peripheral portion 23 of the member 22 by the webs 21, spaced from one another to form air passages 24 between them, and the inner thick end por-- formed entirely through the bearing-mem-- her or supporting sleeve 22, outside of the bar'18, even when the bar 18 is properly se cured in the same; The shell 15 is spaced from the end of the bearing member 22 by lugs 15 (Fig. 3) so that air or gases may pass from the inside of the housing 14 through the space between the shell 15 and housing into the exhaust pipe or flue 13, it

- being understood that the pipe connection 13 may form a communication from the interior of the shell 15 to the chimney, or otherwise. On the outer end of the bearing member 22, lugs 27, are formed for engage ment with the coacting end-lugs 29, on the adjacent crusher or grinder-tooth section, such as section 28 illustrated in Figs. 5 and 6. On the supporting guide-bar 18 a plurality of such crusher or grinder tooth sections 28, are provided each having grinding arms or teeth 30 extending radially therefrom (usually three in number as shown) and also having on the ends interlocking securing lugs 29.

The sections 28, when disposed or strung on the supporting guide-bar 18, have their lugs 29 interlocked with one another, so that the rotary driving of one end section will drive all of the sections. The lugs 29 are staggered relative to the arms 30, and all of the lugs of the several crusher or grinder tooth sections are disposed in identically the same position relative to one another so that when the sections are disposed or strung on the supporting-guide-bar in interlocked position, (it being understood that the spaces between the lugs are adapted to receive the lugs of adjacent sections), the arms or crushing or grinding teeth 30 of the adjacent sections will be staggered relative to one another.

As forming a driving-sleeve for the crusher toothed interlocked grindmg sections 28, there is provided the elongated member 31, shown in Fig. 7, which has a diminished portion disposed on the outside of the wall 0, and an enlarged portion 33 disposed on the inside of the wall 0 and revolubly mounted in an end journal-box 38 supported in such wall 0. The enlarged portion 33 of the member 31 is provided vided with centering webs 40, centering the same on the hollow supporting guide-bar 18, (Fig. 5), which webs are usually three in number as shown, and spaced from one another to form air passages 40 between them; and when all are locatedupon the bar 18, forming a circuitous air-passage by wayof 26, 25., 2 1 and 15 to the exhaust pipe or flue 13.

By having the bar 18 round and with an. unbroken periphery, and providing the ven tilating spaces in the grinder sections themselves, no matter how badly the grinder sections may become warped or fused, theystill may be made to rotate on the bar 18 'for effecting their proper rotation, as when removing, replacing, or lnterlocklng'them.

When the shaft is made with. a bore 19, as shown, air is admitted to said bore through the extreme outer end 19, (Fig. 7

thereby forming an auxiliary cooling means for the shaft; but it is particularly noted that the invention is not limited to the tubular shaft, as this auxiliary cooling means is not necessary for the operation of the device.

In the modification illustratedin Fig. 8,

the housing 14: is shown with itscap re moved, and furthermore the bar 18,"instead of being secured to the bearing member 22 by a screw threaded connection, is secured to such member 22 by means of a pin or key 44, which extends through said bearing member 22 and bar 18, asshown.

It is evidentthat various changes may be made in the details of construction, combination and arrangement of the several parts of the device without departing from the scope of my invention, and I do not intend to limit myself to the exact forms 7 shown.
